' BALL-BEARING.

To all'wkom it concern:

Be it known that'LnFann 'S;-Mon:ro1-r, av United 1 States, residing at made may be of a comparatively simple character, but more especially to provide for maks which constitute the such construction race-ways for the ba s of having that they will be particularly strong integral parts that brace them'agalnst' each other so that com aratively large bearings can be made out 0 thin stock, especially for light Work. The inventionalso involves certain specific ways of bracing the ball ring itself. t

Reference is to be had to the accompanydrawings, in whichigure 1 isa central'sectional view of an annular ball bearingconstructed in accordance fivith this invention show ng it complete;

" -Fig. 2 is a side viewof the same;

Fig. 3 is a view similar to Fig. 1 of another form. of this invention, and

Figs. 4 and 5 are similar views of other modifications.

- In the formof'the invention shown in Q'- Figs. 1 and 2 the parts are shown assembled to constitute a complete bearing, although all the parts are not illustrated in the other figures. The ordinary central member 10 having a groove in which the balls 11 run may be of any ordinary description and will not be described in detail.

The outer raceway for the balls is formed of two annular rings 12. Each of these rings in this form of the invention is farmed of a single piece having a cylindrical outer ,portion 13, a conical inner portion 14, and a flat-edge portion 15. It will be understood, of course, that the particularshape specified is not necessary, that is, the portion 13 will be cylindrical if a cylindrical bearing is to be made.

In the manufacture of this annular mem- Specification of Letters Patent. Application filed; J'uly 1, 1918. Serial No. 242,726.

The principal object of this invention is In the form shown in Fig.

Patented A r. 15,1919.

bera piece ofiflat sheet stock is cutout by dies and shaped to desired. shape, and then the outer flange 13is pressed back from the main portion 14 with outer edgeextending as far as the main ortion 14 does. Then the flange 15'is presse outwardly and is so designed that .it comes just inside the ring 13 and bears against the insideof its ed e.

In this-way any pressure by-the ballson t 1e "conical part 14 is transmitted directly to the outer cylindrical ring 13 by one ;end.of

the cone 14 and through the strut or; bracing member 15. It is transmitted withoutdiminution to the outer edge of the ring- 13 because the end ,of the flange 15 fits'closely against the inner cylindrical surface thereof.

Two of these annular rings are put togetheras shown in Fig.1 with balls in them and then held in position by the'outer casing 16 flangesover its ends as shown at 17.

An extremely strong rigid and durable construction is secured, although in many instances it may be made of lighter stock than I has been the case heretofore on account of the bracing WOT/1011 secured-by the flange 15 against the edge of the cylinder 13. In'this.

wayit is braced within the ball ring itself anda maximum of strength secured.

In the form shown in Fig. 3 the parts are similar and the conical portion =24 is substantrally the same as the conical portion 14- in Fig.1- The outer ring 23 is shorter than in Fig. 1 by exactly the thickness of the metal of'which, the cone is made. The edge flange 25 is longer than in Fig.1 by about the same distance. In other words it overlapsthe end of the ring 23 instead of beingoverlapped by it. v i i 4 the outer portion of ,the annular ring 35 is cylindrical as shown and extends throughout the width of the ring. It is connected by the end portion 35 with the conical portion 34. In this case the brace 35 is integrally connected directly with both the inner and outer members 34 and 33 and it forms an extremely strong kind of brace, but here the contacting ends of the parts 33 and 34 are in engagement within thebody of the device and as two of them are placed together no material amount of strength is lost at this point.

In the form of the invention shown in Fig. 5 the outer ring is entirely omitted and the whole annular ring is formed of the conical portion 44- and the flat edge flange 1'0 Qeasing 1,6 and the ball race sothat foreign 45. The end of. the latter'fits under the easing at 16 and the-opposite endiofthe conical member 44 also engages this casing directly.

In this Way the bracing action issecured; but not in the annular ring itself but only;

ptltthe' edge of the casing 16.

'In' all the forms great strength and'rigidity are secured b the use of comparativ'ely thin metal. he flat bracing flange also fills the space between the edge of ,the

fsubsta'nces cannot enter.
